Title: Picture reader
Inventor: KOTANI MATAHEI
IPC: G03F1/00
Filed: 1983-12-14
Abstract: PURPOSE:To attain reading of a film original with high accuracy by scattering the light from a light source with a diffusing plate and making this scattered light pass through the film original to incident to a sensor via a lens. CONSTITUTION:The diffusing plate 8 is loaded to a forward placing plate 2 at first, a lamp 3 is extinguished and a lamp 9 is lighted. Then the light from the lamp 9 is scattered on the diffusing plate 8, the scattered light transmits through the film original 1 and is made incident to the sensor 6 via the lens 5. In this case, since the lamp 9 is not placed on the optical axis, the direct light transmitted through the film original 1 and made incident to the sensor 6 is prevented because of incomplete scattering of the light on the diffusing plate 8. Thus, the reading of the film original 1 is attained with high accuracy.

Title: Method and device for film formation by sputtering
Inventor: INOUE ISAMU
IPC: C23C14/34
Filed: 1987-09-22
Abstract: PURPOSE:To form a film which is not changed in compsn. ratio in the thickness direction of the film by increasing electric power for sputtering as the film is deposited on a substrate. CONSTITUTION:The electric power to be supplied from a variable voltage power supply 12 to a target 10 in formation of the film by reactive sputtering is so controlled by using an electric power controller 20 as to be increased approximately exponential-functionally from the start of the film formation. The sputtering rate of Te, in the case of the target 10 consisting of Te, increases and the deposition rate of the Te on the substrate 15 increases with an increase in the electric power for sputtering. The chances of reaction between Te and oxygen on the surface of the substrate are then decreased and, therefore, the concn. of the oxygen contained in the film decreases and the change in the concn. of oxygen which arises heretofore is eventually offset. The change in the concn. of the oxygen in the thickness direction of the film is, therefore, not admitted in the formed TeOx film 21 and the corrosion resistance of the film is improved.
